ELEVATOR.

Specification of Letters Patent.

Patented Dec. 7, an.

Application filed August 16, 1910. Serial No. 577,398.

To all whom it may concern:

Be it known that I, ALONZO T AnAlus, a citizen of the United States, residing at Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Elevators, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to elevators for grain, etc., and especially to those parts of the device relating to the association of the cross-conveyor or drag usually employed to receive the material from the Wagon and feed it to the elevating mechanism.

The object of the invention is to provide certain new and improved features relat-' ing to the elevator and crossconveyer or drag having a screw-conveyer-t'o discharge by gravity directly into the open end or boot of the elevator and so mounted upon the boot or open end that it may be swung up out of the path of the loaded wagon moving to position to discharge its'contents into the drag and then swung down to position in rear of the wagon to receive the material therefrom without disengaging the driving connections. N

The invention consists in the novel features hereinafter described and then pointed out in the appended claims.

In the accompanying drawings which illustrate a practical embodiment of my invention: Figure 1 is a view showing in side elevation a device having the features of my present invention with the cross-conveyer or drag in position to receive the material from a wagon shown in position to discharge therein; Fig. 2 is a detail view of parts shown in Fig. 1 with the cross-conveyer or drag swung up to position out of the path of the wagon; Fig. 3 is a top plan view of the cross-conveyer or drag with the inclined sides thereof shown in section;

Fig. 4: is a detail view showing the front plate of the drag; Fig. 5 is a detail view showing the rear plate or hood ofthe drag; Fig. 6 is a detail top plan view of the ad jacent ends of the elevator and drag with some parts in section and all shown upon a larger scale than in the preceding figures; Fig. 7 is a side view of the parts of Fig. 6 with the cooperating sprocket drive and other parts omitted and the shafts in sect1on, and Fig. 8 is a longitudinal vertical sectionalview of the same parts.

Referring to the drawings, the elevator proper may be of any suitable form and construction but preferably comprises a base 10 in-the form of a truck supported upon front andrear wheels, a tubular mast 11 of suitable diameter pivotally mounted upon the truck, and a conveyer comprising an endless series of correspondingly shaped flights 12 moving in the bore of the mast and connected by 'a suitable drive chain 13, the general arrangement and operation of these parts preferably following those set forth in Patent No. 1,117,619, dated Nov. 17-, 1914- based on my companion application filed March 29, 1909, and bearing Serial Number 185,640. The lower end of the mast is Provided with an open end or boot 14 which provides bearings for a drive shaft 15 having an interior sprocket 16 for the chain 13 and extending through the boot so that it may be connected at .eitherend with the tumbling-rod (not shown). of a horse power (not shown) or may be driven by an exterior sprocket 17 having a suitable sprocket chain connection 18 from a suitable motor 19 mounted on the base. When themast is set to the desired inclination the shaft is driven in the direction of the arrows and the flights 12 enter the mouth of the boot and pass down through the grain and up through the mast to deliver the grain or other materialto the desired location, it being understood that a suitable delivery spout 20 may be attached to the d1scharge end of the mast if desired. The boot is provided on each side with an upwardly' extending bracket 21 having a seat or hearing 22, preferably open at lts top, and a wing 23 located in rear of and extending above the associated bearing to support a stop-rod 24 for a'purpose to be presently described.

The grain is discharged into the elevatorboot by a cross-conveyor or' drag comprising a metallic body 25 curved in cross sect on and open at its top for the greater portion of its length and provided adjacentits open top with laterally inclined side-plates or deflectors 26 forming with the body a suitable hopper into which the grain is dumped from the wagon 27. The front end of the dragis provided-with a closure plate 28- into the top of the elevator-boot, and a shield 32.

The lowerwall of the boot is forwardly and upwardly inclined to form its inletopening or mouth, and as shown in Fig. 8 when the drag is in receiving positionthe extension 31 projects into or telescopes with the mouth or inlet of the boot so that when the drag is swung up to permit the wagon to be driven to its discharge position the extension does not disengage from the boot or allow a gap to occur between these parts until the drag has been swung approximately to vertical position, and therefore any loose material remaining in the drag will be guided intothe boot as the drag is lifted or swung up, avoiding any waste of material. Also, the pivotal and telescopic connection of the boot and drag enables theoperator to adjust the angularity of the mast by means of the handle 50 while the machine is in operation without creatingany gap between these parts. 7 Y

The plate 28 and hood 30 are provided With bearingsfor a grain screw 33 in the form of a spiral conveyer which is free to revolve therein but is held against longitudinal displacement therein by a suitable thrust-bearing or box 34 on the plate 28.

.The discharge hood 30 is provided with a pair of rearwardly extendingarms 85 having collars 36, forming bearings for a cross shaft 37 free to revolve therein but held against displacement by suitable means, and the collars 36 extend laterally beyond a the arms and are rotatably supported in the bearings 22 on the boot; asthe collars or bearings 36 may turn about this shaft 37 the entire drag maybe turned up about the shaft and upon the bearings 22 to swingit to-vertica-l position as shown in Fig. 2 to allow the wagon to be driven to position to discharge into the drag which then is swung down to its receiving position in rear of the Wagon as shown in Fig. 1, the drag resting against the stop-rod 24 when turned up.

The screw-conveyer fits the curved body of'the drag and therear end of its shaft is journaled in and extends through the downturned top'wall of the extension 31 of the hood where thecross-shaft 37 and the shaft of. the screw 83 are provided with intermeshing miter gears 38, and one end of the cross-shaft is also provided with a sprocket wheel 39-clriven by a sprocket chain 40 from a sprocket-wheel 41 on the drive-shaft 15, so that the screw-conveyer of the drag is driven from the drive-shaft 15.

By this organization and arrangement of parts the drag discharges directly by gravity into the top of the elevator-boot, feeding the grain directly upon and in the direction of travel of the conveyer flights 12, and the drag may be swung up out of the path of the wagon as it is driven to position to discharge its load and down in the rear of the wagon to receive the material therefrom, the pivotal connection between the drag and boot allowing this movement without wastage of material and without disconnecting any of the intermediate driving connections. Also, the cross-shaft is thus mounted outside the discharge end of the drag so that the gears 38 are not in the chamber or interior of the drag.

The drive chain 40 passes over a suitable idler 42 mounted on a pivotal arm 4-1-3 which may be moved to slacken the chain 40 to allow the latter to be removed from engagement with either of its sprockets, when the drag may then be removed from its bearings 22, the removal of the parts breaking the driving connection with the associated drive shaft and this connection is renewed when these parts are again assembled in place. The open-ends of the bearings 22 may be provided with suitable removable cotter-pins or bolts H to hold the parts against accidental displacement. The chain 18 also passes over an idler 45 mounted on a pivotal arm6.

The mast when not in use rests near its outer end upon the bracket 47 and is swung handle 50. hen the mast is out of operative position the drag or cross-conveyer is detached therefrom, and when the mast is set at the necessary inclination, the drag or cross-conveyer then will be assembled with it in operative relation as shown, its outer end being supported by a suitable leg or stand 51 which may be pivoted thereto as at 52 to fold thereon and held in extended position by a detachable brace 53. lVhen the wagon is to be driven to place the drag is swung up to the position shown in Fig. 2 and after the wagon is positioned the drag is swung down to position in its rear as shown in Fig. 1, the stop constituted by Q driven moves the screw conreyer 83 to discharge the material received by it from the wagon into the open end or boot of the elevator, the material feeding by gravity directly into the boot in the same general direction as the direction of travel of the flights which then carry it along through the mast to the discharge. The shield 32 protects the gears 38 from the grain and deflects the latter toward the bottom of the boot.
